Commercial roofing solutions come in several types such as BUR (built-up roofing), which is used on low-sloped roofs, and steel panels that are typically used on pitched roofs. Of course, there are many other types of roofing materials including TPO (Thermoplastic Polyolefin) and EPDM (ethylene propylene diene terpolymer), both of which are common alternatives for flat or low-sloped roofs. Selecting the right material usually requires the help of a qualified Roofing Contractor because each kind of materials has its pros and cons. For example, EPDM provides a fairly durable roofing solution, but the material has been known to have some shrinkage issues.
BUR is the most common roofing option for commercial buildings because it is budget friendly and easy to repair. BUR uses multiple layers of a roofing membrane such as roofing felt or tar-paper, and each layer is coated with a layer of asphalt. This creates a thick protective covering that is easy to repair. The final covering on BUR is a layer of aggregate such as gravel. This provides weight to keep the roof in place and traction for those times that the roof must be walked over. One concern with BUR is that the roof can be easily damage. For instance, whenever technicians need to service air conditioning systems, there is a chance that the roof might be torn. Letting an experienced commercial roofing contractor in Emporia, KS inspect the roof on a regular basis reduces the chance of leaks and possible damage to the building or its contents.
A more viable option for low-sloped roofs is TPO. This polymer based product is placed in long strips. Each seam is welded with automated equipment, so they are strong and durable. TPO roofs can survive a variety of weather conditions, and the material lasts for many years. Repairs to the roof often depend on the type of damage. Simple tears can usually be welded by hand while more extensive damage requires patching with replacement pieces. Sealing around roofing details is usually done with special sealants or caulks. If the company budget cannot handle the cost of TPO, then there is the option of PVC (polyvinyl chloride) roofing sheets. PVC is not quite as durable as TPO, but it still functions very well.
